* a specification.

My object is to facilitate the transfer of mail-matter and baggage toand from railway-cars and diminish the manual labor rcquircd in handlingmail-bags and other articles that can be placed in a movable truck.

My invention consists in the apparatus hereinafter set forth, pointedout in my claims, and illustrated in the accompanying drawings, inwhich- Figure 1 is a side elevation of a movable .ruck and mechanism Forraising and lower ing the platform relative to the floor of arailroad-car. It also. shows end views of a smaller truck adapted to bemoved in and or baggage car, as required for transferring their contentsto and from a car. Fig. 2 is a front view of the main truck in positionas required to be connected with a car or a track. Fig. 3 is a bottomview of the main truck and shows the construction and application ofmechanism for raising and lowering the platform relative to the trot-loWheels. Fig. 4 is an enlarged sectional View of the means for raisingand lowering the platform and the manner of combining; it with atruck-axle and the corner of the platform.

T he nun'ieral l0 designates the front axle, and 12 the rear axle,mounted on trucl- A. pole 13 is connected with the front axle to be usedin manually moving the truck. Standards 14 are fixed to the end portionsof the axles and provided with internal screws 15 in their top portions,as shown in F 4. A screw 16 is litted in the internal screw 15 and abevel-gear 17 fixed to its top. A frame 18, adapted to be fixed to theunder side of a platformfis provided with a sleeve l9,.adapted to beplaced on the tubular standard 14 in such a manner that the trains 18can he raised and lowered by rotating the screw 16.

Each corner portion of the nlatform 20 has a frame 18 fixed thereto, assnown in 2%, or in any suitable manner, as required for plaoin thesleeves if! on the tubular standards 1 I K To simultaneously rotate thetour screws 16 in the internal screws 15 in the standards l4, a shaft.21 is mounted in bearings N, as shown in the front end oi Fig. 3, or inany suitable way, as required For engaging bevel 6o gear-wheels 23 withbevel gear-wheels 17 on the ends oi the screws 16, so that the shaft andbevel-gears can be operated by a rotatablc shaft 24, mounted inbearings, as shown in Fig. 3, and provided with a fixed worm 25 '3 toengage a gear-Wheel on the shaft 21. To transmit prover and motion fromthe shalt 2: to the bevel-gears at the rear of tho platfor as requiredto actuate the screws 16 in t tubular standards 14, shafts 27 and 33mounted in bearing 1%, as shown, or in any suitable ivy, and bevel gears12S) tim 4 their ends to iic engaged by the here 17 on the top ends ofthe laws l6, 1-.- in 3. it is obvious that by rot handle 30 (ii theshalt .24 all the screws; it} will be rotated at the same time. asrequired to raise or lower the platform.

The top of the platform 20 has fixed transverse bars 31 for keepingtrucks 32 separate on its top: These minor trucks are prcir l n LG ablyprovided with jointed axles 33 to facilifate" moving the trucks and in lng short turns. Handles 34 on t reir ir n adapted to aid in moving, themt. sides are composed of hers 3o, acl connected with the trucks b meanor bolts and hooks o7 or in on; Sil

required for opening and clo of the trucks for placing bags, lco,therein.

To connect the platform tensions 38 are hinged or cthe ably connectedwith pie L a orni shown in h a car, as 5l10' Fig. 12, in such a mannerti when lie a in a horizontal position tl ior troclts c be moved directfrom tho i wk 20 into a or vice versa.

Having thus set forth invention and the ment, and combination of all.the par" practical utility and 0 peration thereof a readily understoodby ra ri'iad men and others familiar with transl .rring mailbag), 15:5

the purpose of IN" construction,

What I claim as new, and desire to secure by Letters Patent, is

1. A four-wheeled truck having tubular standards fixed to the endportions of the axles and provided with internal screws in their topportions, frames adapted to be fixed to the corner portions of thebottom of a platform and provided with sleeves adapted to be placed onthe tubular standards, screws seated in the tubular standards and meansfor rotating said screws simultaneously, ar ranged and combined tooperate in themanner set forth for the urposes stated.

2. A tour-wheeler truck having tubular standards fixed to the endportions of the axles and provided with internal screws in their topportions, frames adapted to be fixed to the corner portions of thebottom of I a platform and provided with sleeves adapted to be placed onthe tubular standards, screws seated in the tubular standards, means forrotating said screws simultaneously, comprising bevel gear-wheels fixedto the tops of said screws in the tubular standards, a shaft in bearingsat the front portion of the bottom of the platform and bevel-gears fixedto its ends to engage the bevel-gears on the top of said screws andmeans for rotating the shaft, arranged and combined to operate in themanner set forth for the purposes stated.

3. A fourwvheeled truck having tubular standards fixed to the endportions of the axles and provided with internal screws in their topportions, frames adapted to be fixed to the corner portions of thebottom of a )latform and rovided with sleeves adapte to be placed onthetubular standards, screws seated in the tubular standards, means forrotating said screws simultaneously, com prising bevel gear-wheels fixedto the tops of said screws in the tubular standards, a shaft in bearingsat the front portion of the bottom of the platform and bevel-gears fixedlo its ends to engage the bcvel-gears'on the tops of said screws, arotatable shaft, in right-angled position to said shaft, provided with aworm. and a gear-wheel on the first-mentioned shaft engaged by saidworm, arranged and combined to o ierate in the manner set forth for lthe purposes stated.
